The Expectant Mother Asks the Nurse How CMV Is Diagnosed

The expectant mother asks the nurse how CMV is diagnosed in infants. The best answer by the nurse would be:

A) "Check for the presence of IgM CMV antibodies in cord blood, which identifies congenitally infected infants; there is another test for detecting antibodies in the baby's blood."
B) "Inspect for the presence of symptoms characteristic of this disease."
C) "Conduct a test on the fluids of the eye, which are carefully collected on a swab and placed in a special tube."
D) "Inspect for the effects of the IgM CMV antibodies, which are evident in special tissue tests done in utero or shortly after birth."
